The kinetic coefficient of friction is 0.3 and the static coefficient of friction is 0.4. (36 points) Page 2 of 4 B A 30° 40° P=15 lbf Additional space for problem 2 3. (a) What is ψ in the equation θ = ψdr / d r tan 1 ? (4 points) (b) Why is ψ useful or important? (4 points) Page 3 of 4 4. The horizontal slider A moves with a constant velocity v = 2 m/s and has a vertical rod attached to it. The second slider B, with pin P attached, slides on the vertical rod attached to A. Pin P on slider B follows the slot defined by the equation ( 29 x sin 2 . y π = . When point P is at x = 0.25 m, find the magnitude and direction of its velocity and the magnitude and direction of its acceleration. (28 points) Page 4 of 4 A B...
